Complex as a built-in does nothing of interest to anyone except a cute syntax for literals that nobody uses (how many remarkable complex literals could you imagine?) About "with"... see above before I die of a heart attack.

Can you give us more detail?

I'm still hoping that one day D will be able to implicitly cast to scope invariant... such as when calling pure functions with non-shared data.

On an almost unrelated note, D currently makes it far too easy to share non-shared data. Kicking off threads with non-unique unshared data is unsafe but works without casting. That really should get fixed.
